Why is my Western blue-eyed grass not blooming?

Western blue-eyed grass needs specific light conditions to produce its signature blue flowers. Lack of blooms usually points to a need for more direct sun.

Check these first

  1. Measure the hours of direct sunlight the plant gets.
  2. Check if the plant is crowded by other taller plants.
  3. Look for signs of new flower buds at the base.

Likely causes

  1. Insufficient Light

    Most likely

    How to tell: The plant looks healthy and green but never produces flower stalks.

    What to do: Move your plant to a spot that receives at least 6 hours of direct sun daily. If it is in deep shade, it will focus on leaf growth instead of flowers.

  2. Improper Dormancy

    Possible

    How to tell: The plant seems to stop growing or looks tired during the wrong season.

    What to do: Ensure the plant experiences a natural cooling period if you are in a mild climate. Do not over-fertilize, as this encourages leaves over flowers.
